Nanomolding Based Fabrication of Synthetic Gecko Foot-Hairs
نویسندگان
چکیده
This paper proposes two different nanomolding methods to fabricate synthetic gecko foot-hair nanostructures. The first method uses Atomic Force Microscope (AFM) probe indented flat wax surface and the second one uses a nano-pore membrane as a template. These templates are molded with silicone rubber, polyamide and polyester type of polymers under vacuum and the template is peeled off or etched away. Results show that these synthetic nano-hair prototypes have adhesion close to the predicted values for natural specimens (around 100 nN each).

متن کاملFabrication of gecko foot-hair like nano structures and adhesion to random rough surfaces∗
In this work the effect of substrate roughness on the adhesion of gecko foot-hair like nano structures as opposed to solid elastic materials is described and models of both synthetic nano-hairs and hair-substrate interaction are developed. First, by combining linear beam theory and geometric constraints, a nonlinear elastic model for the hair is derived. Then it is shown how for a given random ...
متن کاملSolid state and materials research news: phys. stat. sol. (RRL) 4/2007
Mimicking the agile gecko, with its uncanny ability to run up walls and across ceilings, has long been a goal of materials scientists. Researchers at Rensselaer Polytechnic Institute and the University of Akron have taken one sticky step in the right direction, creating synthetic “gecko tape” with four times the sticking power of the real thing. The researchers describe a process for making pol...
